opening 3 ofthe box 2.

outer end of the shaft 13, as shown. By grasping the knob 21 and pressing down upon the outer end of the lever 22 its end 23 may be moved' out of the groove 24, and the pinion 14 may be 'slid longitudinally upon the shaft-13 to move said pinion into Aand out of mesh with the driving-gear 18.

It will be understood that when the pinion upon the shaft of the roller is engaged with its driving-gear the pinion upon the shaft of the roller 6 is disengaged' gear, ls that the apron or belt 4 will be driven positively in one direction or the Each ofthe shafts 19 has secured upon it a ratchet-wheel 25, which is adapted to be engaged by a pawl upon a suitable operating-lever. As shown, the ratchetwheel on the 'shaft 19 at the left-hand end of the box is engaged by a spring-.actuated pivoted pawl 26, mounted upon a lever 27. The latter is pivoted, as at 28, at one of its ends and has an offset portion 29 to clear said shaft 19. The opposite or free end of said lever carries the armature 30 of an electromagnet 31, which is mounted within the box or casing 2. The lever 27 may be elevated by a spring or in any other suitable manner; but, as shown, I have provided a weight 32, which is attached to one end of a cord or other lexible connection 33, passed. over a pulley, 34, and connected to the free end of the lever 27. Whenthe electromagnet 31 is energized, its armature will be attracted and the lever 27 will be swung downwardly to cause its pawl 26 to slip over the teeth of the ratchet-wheel, and when said magnet is denergized the weight 32 will elevate the lever and cause the pawl 26 to actuate the ratchet-wheel, the gear-wheel 18, the pinion 14', and hence the shaft of the roller 5, sufficiently to cause the apron to pre sent the name ofthe next street in front of the The ratchet-wheel 25, which' is at the right-hand side of the box and which controls the roller 6, is actuated by a similar spring-seated pawl 35, which is mounted upon a lever 37, pivoted at 38 and havin y 19, pon the free end of the lever 37 is suspendeda weight 39, which is adapted to actuate said shaft in one direction; but it will be understood that a spring or any other` suitable means may be substituted therefor. The lever 37 is actuated in the opposite rdirection by a lever 40, which is pivoted intermediate its ends, as at 41, within the'box 2 and has one of its end s engaged with` theunder sideof 4the free end of the lever 37. The opposite end 42 of the lever 40 carries the armature of an electromagnet 43, which is mounted centrally in the rear portion of the box 2. a

' It will be seen that when the magnet 43,is

energized the lever 40 will -be swung to eletethe lever '37, so that its pawl35 will slip from its drivingan ofiset portionto clear the shaftshafts over the teeth of the ratchet-wheel 25,. and that when it is denergized the Weight 39 will lower the lever 37, and thereby cause the roller 6 to be actuated a distance suici'ent'to bring a new name before the opening 3.

l The v two electromagnets 31 and 43 are. simultaneously energized by the closing of an electric circuit 44, in which the areineluded. This circuit 44 also inclu es a circuit-closing device which has one of its members carried by the trolley-pole of the car in which the indicator is mounted and its coacting member upon theY trolley-wire 45l in the center'of or adjacent to a street crossing 4or station. The circuit'eclosing member upon the trolley-pole 46 is in the form of a lever 47, which is mounted upon an insulated pivot 48 and has a weight 49 at its lower end and a beveled portion 50 at its upper end. This beveled portion is adapted to engage a contact member 51, which is secured upon the trolley-Wire, as shown in Fig. 5 of the drawings. This contact member. is preferably formed by bending and uniting one or more pieces of wire, to form spaced parallel contact-bars 52, which have flared outer ends, so that the beveled portion 50 of the contact-lever 47Inay readily enter between thein. lf desired, this contact meanber or device may be duplicated upon the opposite side of the trolley-pole, as will be readily understood. While this form of circuit-closing device. is preferably employed when the indicators are used upon trolleycars, it will be understood that the magnets 31 and 43 maybe actuated in any other suitable manner, either manuallyor automatically.

From the, foregoing description, taken in connection with the accompanying drawings, the construction and operation of the inven- IOO IOS-

tion will be readily understood without Iequiring a more extended explanation.

Various changes in the torni, proportion,

and the minor details of construction may be resorted to without departing from the princi ple or sacrii icing any ofthe advanta es of this invention as defined by the appen ed claims.

Having thus described my invention, what l cla'im as new, and desire to secure by Letters'latemv, 1s v 1. In adcvice et the character described,
